Kinect v2 Multiple Player "trigger" upon detection

Hey everyone. I’m working on a project with a particle system driven by a Player detected by a Kinect v2. I want to drive a second particle system when Player 2 enters the Kinect’s camera range, but to have that particle system start emitting / showing up ONLY if Player 2 steps into the camera range.

I already have the first one done and it’s looking good, but when adding a second one there is a second particle system that stays still until Player 2 walks in. I want it to appear only when Player 2 walks in.

I’m new to TD, this is my first project, so more detailed answers would be appreciated (which CHOP / TOP / …) to use, what techniques, what i should look into in the documentation etc

Thank you
